code block et Gtk

Bonjour
J'installe Gtk+ sur code block et j'ai le pb suivant
---------------------------
Erreur
---------------------------

Gtk-ERROR **: Incompatible build!
The code using GTK+ thinks GtkBox is of different
size than it actually is in this build of GTK+.
On Windows, this probably means that you have compiled
your code with gcc without the -mms-bitfields switch,
or that you are using an unsupported compiler.
aborting...

---------------------------
OK
---------------------------

Que faire svp?
A+
